Pacemen Umar Gul and Mohammad Sami each took three wickets as Pakistan posted a comfortable six-wicket win over Sri Lanka in the first one-day international in Pallekele on Thursday.

Man-of-the-match Gul finished with 3-24 and Sami with 3-19 before Pakistan achieved a rain-revised target of 135 with more than seven overs to spare in the day-night match for a 1-0 lead in the five-match series.
